05 duramax owners. Questions

Post by phx450 »

I have a 2005 duramax crew cab 4x4 lifted on 35s. The truck is awesome, no problems, no issues.

My question is during towing, especially in the summer the fan kicks on. for any of you who have the same truck you know the fan im thinking of. The truck still tows fine, its just loud and annoying. What can i do to fix it?

Fix it? There is nothing wrong with your truck, the clutch fan is doing it's job. It's designed to pull a lot more air when towing in the heat, these diesels make a lot of power and need the extra cooling. Yeah it's noisy but it's perfectly normal.

I understand its doing its job, just curious if could be quiet.

On that Diesal Website i have seen a couple kits that claim more cooling from the fan setup they have as well as more HP.

Love the truck but like it more during the winter!

Here's what ya do.

1) Remove the radiator cap.
2) Pull the Dmax out into the driveway.
3) Pull the new Dodge or Ford in(your choice).
4) Replace radiator cap.

Problem solved. :lol:

It wouldnt make the hills with a ford or even worse a dodge pulling it!

HA!
I tote my trailer 14,000lbs loaded anywhere up virtually any hill at 70+...... Could go much faster except up hills, but I don't think it's safe going over 70 with 21,000 lbs of truck and trailer.

With a Dodge, although I would like to have your Allison! :lol:

I can proudly say that I have NEVER owned a Vortec ANYTHING. Although I do own a Chevy race car and a Chevy pickup from the 70s. I can safely say I have no idea what you are talking about. Must be thinking of someone else.(?)

nothing. its part of the deal. my FORD that pulls my trailer just fine, makes the same noise when the fan kicks on as well. its a diesel, and they thrive on heat. too much, however, and its bad news. thats why the fan kicks on. you could always remove the fan, but your gonna overheat, but duramaxx engines are famous for that anyways with a fan. overheating is not good on a duramaxx, especially with the aluminum heads. consider the fan a blessing...i know i do in my ford. it could be twice as loud, and i wouldnt care..
